Abstract
Image super resolution is a signal processing technique to post-process a captured image to retrieve its high-resolution version. Majority of the conventional super resolution methods fail to perform in presence of noise. In this paper, a noise robust reconstruction based single image super resolution (SISR) algorithm is proposed, using alternating direction method of multipliers (ADMM) and plug-and-play modeling. The plug-and-play prior concept is incorporated to the two variable update steps in ADMM. Therefore, a fast SISR model and a denoiser are used in ADMM to implement the proposed robust SISR scheme. The experimental results show that the noise performance of the proposed approach is better than the conventional methods. The impact of parameter selection on the performance of the algorithm is experimentally analyzed and the results are presented.
